DUMPlNe-wAeoN.

SPECIFICATION forming part of Letters Patent No. 678,470, dated July 16,1901. Application nea December' 6,1900. Santino. 38,854. (Nomaden T0 allwhom/ it 11m/,y concern:

Be it known that I, THOMAS HILL, a citizen of the United States, and aresident of Jersey City, in the county of Hudson and Stateof New Jersey,have invented certain new and useful Improvements in Dumping-Vagons, ofwhich the following is a specication.

The invention relates to improvements in dumping-wagons, and pertainsmore particularly to the novel pedestal construction hereinafterdescribed and claimed, adapted to receive the trunnions which projectfrom the sides of the vehicle-body.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which- Figure 1 is a side elevation, partly broken away, of a cartequipped with a pedestal construction embodying the invention. Fig. 2 isa central vertical longitudinal section, on an enlarged scale, of thepedestal construction and its supporting-frame. Fig. 3 is a horizontallongitudinal section of same on the dotted line 3 3 of Fig. 2. Fig. 4 isa detached top view of the longitudinal bar which bears upon the springsand receives the trunnion. Fig. 5 is a bottom View of same,and Fig. 6 isa bottom view of one of the pedestal-caps.

In the drawings, 10 designates the usual wheels, 11 the sideframes,which extend frontward to formV the booms 12, and'13 the cart orvehicle body, also of usual construction, having the trunnions 14projected laterally from its sides and constituting the `pivotal pointson which the said body may turn rearward when it is desired to dump thesame. Upon the side frames are bolted the pedestal structures made thesubject of. this application and each comprising the base-plate 15, thehollow pedestals -16 16, the springs 17'- within said pedestals, thelongitudinal bar 18, having the bearing 19 for the trunnion 14, and atits ends resting on said springs 17, the caps 20 on the upper ends ofsaid pedestals 16, and the rods 21, which extend centrally through saidpedestalsl6, springs 17, ends of bar 18, and caps 20.

The base-plate l5 is of suitable size and is in one integral castingwith the hollow pedestals 16 16, the latter when in the casting beingopen both at their upper and lower ends.

The plate 15 is secured upon the side frames 11 by means of bolts 22 andthe aforesaid rods 21, and said plate being integral with the hollowpedestals 16 16 supports the same. l The pedestals 16 16 are cylindricalin cross-section and have at their facing sides the vertical slots 23,which are encompassed at their sides and bottom by the flanges 24, whichafford broad wall-surfaces to said slots 23 and also strengthen thepedestals.

Within the pedestals 16 16 are conlined the coiled springs 17, whoselower ends bear upon the side frames 11 or upon small protecting- Theends of the bar 18 are circular and sub-.

stantially correspond at their edges with the inner walls of thepedestals 16, and said ends of the bar 18 are wider than the slot-s 23,and hence could not be pulled horizontally outward through said slots,in which, as is apparent, the bar 18 is adapted to have a verticalmovement.

Upon the upper ends of the pedestal 16 are the caps 20, which have apolygonal central aperture 28 and two concentric edge iianges 29 29 topass upon and hold between them the upper edges of the pedestals 16,said fianges 29 29 affording strength to the caps 2O and effectuallyresisting any tendency of said caps to move laterally when the cart isin use. the pedestals 16 and also the upper ends of the slots 23, andthey retain the ends of the bar 18 securely within the pedestals 16 16without interfering with the vertical movement of said bar. A The caps20 are fastened upon the upper ends of the pedestals 16 by means of thebolt- `rods 21, which pass downward through the caps 20, the ends of thebar 18, the springs 17 and the side frames 11, said bolt-rods 21 hav-The caps 20 close the upper ends of IOO ing a head to bear upon theupper end of the caps 2O and being threaded at their .lower ends toreceive the securing-nuts below the lower surface of the side frames 11.The upper portions of the bolt-rods 2l are provided with the polygonalsurfaces 30 to engage the walls of the apertures 28 in the caps 20, thesaid polygonal surfaces 30 in connection with the walls of the apertures28 constituting means for preventing the turning of the boltrods 2l. Itwill be observed upon reference to Fig. 2 that the bolt-rods 21 passdownward centrally through the hubs 26 on the lower sides of the ends ofthe bar 18, and hence the' said rods 21 aid in guiding the bar 18 duringits vertical movement, the walls of the apertures through the hubs 26forming extended guiding-surfaces to move on the rods 21.

The trunnions 14 at the opposite sides of the body 13 are retainedwithin the bearingapertures 19 of the bars 18, and hence the saidtrunnions have a spring bearing by reason of the support afforded to thebar 18 by means of the springs 17, and during the movement of thevehicle the bar 18 will have a vertical play, being guided in itsmovement by the walls of the slots 23, the surfaces of the bolt-rods 21,and the inner walls of the pedestals 16, the said bar 18, while beingpermitted to have a vertical movement, being eifectually prevented fromhaving endwise movement.

The construction hereinbefore presented is of that durable characterwhich enables it to withstand the severe usage to which the carts areordinarily subjected, and in addition the structure is such that itembraces the minimum number of parts and is capable of being constructedand applied in a comparatively inexpensive manner. It is to be observedalso that the details of the parts of the pedestal structure are sodisposed and arranged with relation to one another as to prevent endwisethrusts against the bar 18 from having any prejudicial effect on thestructure as a whole, the strains following any endwise thrusts on thebars 18 being so distributed through the structure as a whole as toenable the structure to withstand the same.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with the running-gear and vehicle-body, the latterhaving the side trunnions 14, the pedestal structure secured to the sideframe and comprising the cylindrical pedestal members 16, the base-plate15 ,integral with said pedestal members 16, the
